LUBRICATING-OIL CAN.

Application filed February 15, 1927. Serial No. 168,400.

This invention relates to oil cans'for oiling bearings and the like and the general object of the invention is to provide an o1l lcan having a can proper and a nozzle and provide means whereby air pressure may be used to force the oil out of the nozzle when desired;

Another object is to provide a can of this character so constructed that lthe tube connectin the oil can with the nozzle constitutes a andle whereby the oil can' may be held, passage through the nozzle being conf trolled by a valve whose handlii's disposed adjacent said pipe so that the handle mayv be conveniently operated while the nozzle is Vbeing directed to any particular point.

-Other objects have to do with thefdetails ,of construction and arrangement ofparts to appear more fully hereinafter.

My inventionv is illustrated ,panying drawings wherein d Figure l is an elevation of my improved oil can-partly broken away so as -to show the interior construction; Fig. 2 is an elevation but withthe can in the 4.accomproper and pump in section;

Fig. 3 is a' section von the line 33 of Figure'l; i

Fig. 4 is an elevation of the lower end of `the pump showing the manner of holding the valve thereon.

Referrin to these drawings 10 designates the can itse This can is provided with the screw-threaded neck 11 through which is inserted the barrel 12 of an air ump, this pump having the screw-threade flange 13 engaging the screw-threaded neck l1. i Extending upward fr om the can and opening thereinto isa pipe 14 which terminates in a curved T15. Connected yto this T and preferably integral therewith is the nozzle 16. The lower end of the T is screwthreaded and enga g these screw-threads is the screw-threagdidzflange of -a cap 17. The upper end of the T is formed with a valve seat 18 and operating within the T is a valve stem 19 carrying the valve 20. A'

, cap 17 and is provided with the head 22.

The lower end of the T 15 is provided with an outstanding ear 23 and pivoted to this ear is the valve operating lever or handle 24 which is formed of stamped sheet metal.

of any suitable character. of the barrel is formed with a perforation The sheet metal is bent upon itself longitudinally and at itsA pivotal end the two thicknesses ot' metal are brought close to.` gether to provide the opposed ears 25 which embrace the ear 23 and are pivoted thereto by a cotter pin 26. The lever or handle is cut away at 27 and the stern 19 extends down between the two thicknesses of metal and the head 22 ius disposed within this cut awa portion 27.k It will be obvious that as the andle is drawn toward the tubular portion 144 the valve will be opened and when this handle' or lever 24 is released, the valve will be closed. f f v For the purpose of forcing air into the upper portion of the can 10 I provide the air pump barrel 12 which, as beforel stated, extends downward inthe can nearly to the bob tom thereof. This pump barrel has operating within it thepiston 28 having a piston rod 29 which extends out through the top or cap 30 of the barrel. This piston may be The lower end or aperture 31 and `disposeduover this aperf ture is a leather /washer 32 constituting a valve. Thiswasher is supported. in a cruciform holder 33 having four upwardly extending lugs. Two of these lugs 34 are relatively long and are soldered or otherwise attached to the exterior of the barrel 12. The other two lugs 35 are short rand are bentv over upon the face of the washer. This permits the leatherwasher 32 to be readily replaced if it should become worn by simple bending up these prongs 35 and re lacing the washer. Upon av down stroke ofptihe piston, the washer will be forced away from the air within the can above the oil. Then when opened by simply depressing the handle 24.

it is desired to luse the can, the valve 20 is As soon as this handle 4is released, the flow of oil will be stopped. The pipe 14 constitutes a handle for holding, carr ing, and mani ulating the oil can andthe andle 24 may e operated by the fingers or thumb4 of the vsame hand. Thus only one hand need be used when oiling bearings. Obviously the can may be made of any desired size and for use with any kind of oil. The mechanism is extremely simple and the device maybe cheaply produced.

The parts and features of the invention are so arranged and assembled that the free end portion of the operating handle is disposed approximately parallel with the handle pipe and thus the operator when grasping the nozzle handle 14 will have his ngers disposed transversely across the valve operating handle.

Actual practice has shown that with one depression of the piston the device may be used `for oiling as many as two hundred bearings. Of course, the device may be used for oiling bearings, joints, drip cups, and for all other purposes for which an oil can is adapted.

It will `be of course understood that the piston 28 is made like the ordinary tire pump piston sothat upon an upstroke of the piston air will flow downward past the piston itself into the lower portion of the cylinder 12 and upon a downstroke of theI piston the compression of the air beneath will cause the piston to fit tightly against the wall of the cylinder 12 and cause the air beneath the piston to be forced out through the opening 31.

I claim l. An oil can including a can proper, a nozzle pipe connected therewith and serving as a handle, a. spring actuated Valve -within the nozzle, a handle grip pivoted to the nozzle pipe for shifting the valve from its seat against the action of a spring, and having an endportion disposed approximately parallel with the nozzle pipe, and means for pumping air into the upper end o the oilcan. Y

2. An oil can comprising a canI proper having` a pipe projecting outward from the n side thereof and then extending .parallel to the axis ofthe can to form a handle therefor, said pipe terminating in a T having a curved portion, a nozzle mounted upon theV T, a cap closing one end of the T, a valve stem extending through the cap, a valve in the nozzle carried by said stem, a spring urging the valveelosed, a valve handle grip pivotally mounted upon the nozzle pipe and having a free' end portion disposed approxi-v matelyV arallel with the nozzle pipe, and a pump etachably engaged with the top of the oil can.

3. An oil can comprising a can proper having means whereby air may be pumped into the can, a handle pipe extending from the side of the can, upward above the top of the can and there @formed with a T, a. nozzle mounted upon the T, a springl actuated valve within the T acting to prevent the tlow of oil through the nozzle, an ear mounted on the pipe, and a handle grip for the valve' formed of a strip of metal bent upon itself longitudinally to provide two approximately parallel portions at its upper end embracing the valve stem and operatively engaged therewith and embracing the ear and pivoted thereto and having an end portion disposed approximately parallel withthe handle pipe.

4. In an oil can of thetcharacter described, a can proper having a nozzle, a manually operable valve controlling the ow through said nozzle.` and means for pumping air into the can comprising a cap dctachably closing the end of the can, a barrel carried by the cap and extending longitudinally through E .the can, the lower end of the barrel having an aperture, a cruciform strip having two relatively long legs diametrically opposed and attached to the barrel, a washer supported by the cruciform strip below the vaperture in the barrel, the strip having two short legs bent over to hold the Washer in place.

In testimony whereof I hereunto an'ix my signature.

GEORGE MERZ.
